Symptoms of febrile seizures in children

Febrile convulsions in children are nothing new nowadays, and the incidence rate is still very high. Febrile convulsions in children can cause many diseases, among which brain diseases are the most serious. However, many parents still do not understand febrile convulsions in children and do not know what they are like when they occur. So today I will introduce to you in detail the main manifestations of febrile convulsions in children.

Febrile seizures can be divided into two types: simple and complex, depending on the age of onset, severity of seizures, and neurological signs. The simple type usually presents between 4 months and 4 years of age. Convulsions occur soon after high fever and last for 5-10 minutes. Convulsions are systemic, the nervous system is normal before and after the attack, and the EEG is normal one week after the fever subsides. This type accounts for the majority of febrile convulsions and has a good prognosis. Complex seizures last for more than 15-30 minutes. The seizures are systemic or focal, and there may be neurological signs. Seizures occur 2 or more times during one fever. They may occur in children under 6 months old or over 6 years old. This type is only a minority.

If the convulsion is caused by hypocalcemia, the child may be conscious. If the patient convulses again before consciousness is restored or the convulsions persist, it indicates that the condition is serious and may lead to death due to cerebral edema or respiratory failure. If the location of the twitch is localized and constant, it often has localization significance.

3. Abnormal actions

Neonatal seizures are often manifested by a variety of abnormal movements, such as apnea, irregular breathing, staring eyes, paroxysmal pallor or cyanosis. Convulsions in infants and young children sometimes only manifest as twitching of the corners of the mouth or eyes, twitching of one limb, or alternating twitching of both limbs. Neonatal convulsions are rarely manifested by systemic convulsions, but are often manifested by irregular or paused breathing, paroxysmal cyanosis or pallor, staring eyes, nystagmus, blinking movements, or sucking and chewing movements.

Status convulsiveus: A seizure lasts for more than 30 minutes, or consciousness cannot be fully restored between seizures. It is a critical type of convulsion. Prolonged convulsions can cause high fever, hypoxic brain damage, cerebral edema and even brain herniation.
